Description

Description: TECHNICAL FIELD [0001] The present invention relates to a seedling transplanter for removing a seedling of one strain from a seedling placed on a seedling mounting table and transplanting it to the ground.

[Conventional technology]

In the seedling transplanter, the seedling mounting table is fixed to the lower end side of the seedling mounting table that moves left and right, and the lower end of the seedling placed on the seedling mounting table is supported by the receiving surface of the seedling receiving tool, and the swiveling seedling is rotated. A configuration is used in which a planting tool descends through a seedling opening of the seedling receiving device, takes out a seedling of one plant, and plants it on the ground.

Also, the one whose outer shape is close to that of the present invention is
As in JP-A-3157, there is a type in which the receiving surface rotates around a lower horizontal axis.

[Problems to be solved by the invention]

In this type of seedling mounting machine, seedlings planted on a mud surface may tilt forward or backward due to factors such as a change between plants.

The present invention adjusts the posture of the seedling before transplanting by changing the angle of the receiving surface of the seedling receiving device in accordance with the change between plants, thereby reducing the inclination (planting posture) of the seedling on which the mud is planted. To adjust.

[Means for solving the problem]

The present invention solves the above-described problems, in order to solve the above problem, a seedling receiving tool 10 provided on a lower end side of a seedling mounting table 9 that moves left and right and receives a lower end of a seedling mounted on the seedling mounting table 9 on a receiving surface 10b, In the seedling planting machine, the seedling receiving device 10 is provided with a seedling receiving device 10 that swivels through a seedling opening of the seedling receiving device 10, and the angle of the receiving surface 10b is changed in conjunction with a control device between the plants. This is an adjustment device for the planting posture.

[Function and effect of the invention]

Since the present invention is configured as described above, when the seedling transplanter provided with the seedling is propelled in the paddy field, the seedling placed on the seedling mounting table 9 is received by the receiving surface 10b of the seedling receiving tool 10. Then, the seedling mounting table 9 moves left and right on the receiving surface 10b by the left and right movement. Here, since the seedling-planting tool 11 is swirling downward through the seedling opening of the seedling receiving tool 10, the seedling-planting tool 11 is sequentially picked up by one plant and planted on the mud surface.

Seedlings planted on the mud surface in this way may lean forward or backward when the inter-strain is adjusted. Therefore,
Since the receiving surface 10b of the seedling receiving device 10 is adjusted in angle with the inter-strain adjustment, the posture of the seedlings taken out by the seedling planting tool 11 is changed, so that the posture planted on the mud surface also changes, and the posture of the seedlings stands upright. In this way, good rice transplanting work can be performed regardless of inter-plant adjustment.

〔Example〕

 Next, a rice transplanter embodying the present invention will be described.

As shown in FIG. 1, the traveling vehicle body 1 includes an engine 2, front wheels 3 driven by the engine 2, and rear wheels 4. A rice transplanter 5 is connected to a rear portion of the traveling vehicle body 1 by a link 6 to form a rice transplanter.

The rice transplanting apparatus 5 includes a gear box 7 into which the rotation of the engine 2 is introduced by the input shaft 6, and a seedling table 9 which tilts forward so that the bottom surface 8 faces obliquely upward and moves left and right on the gear box 7. An L-shaped seedling receiving device 10 provided at the lower end of the seedling mounting table 9 to support the lower end of the mat seedling on the seedling mounting table 9; 11 and a float 12 provided under the gear box 7 and sliding on a mud surface.

As shown in FIG.
Is provided. Seedling receiving device 10 is a lower surface continuous with bottom surface 9
The horizontal rod 1 is formed in an L-shape with a receiving surface 10b orthogonal to the front end 10a, and the upper end of the lower surface 10a rotates around the horizontal axis 14.
Installed on 3. The seedling receiving device 10 has a receiving surface 10b.
From the bottom to the lower surface 10a (not shown), and the tip of the seedling plant 11 passes downward through the seedling opening.

A vertical lever 15 is attached to the gear box 7 with a central pin 16, and the lower end of the lever 15 is pulled forward by a spring 17. The lower end of the lever 15 and the arm 18 of the seedling receiving device 10 are linked by a link 19. It is connected.

Both ends of the outer wire 20 are fixed to the traveling vehicle body 1 and the gear box 7, and both ends of the inner wire 21 passed through the outer wire 20 are attached to the operating rod 23 near the seat 22 and the upper end of the lever 15.

When the rice transplanter thus configured is operated in a paddy field with a mat seedling placed on the seedling mounting table 9, the float 12 slides on a mud surface as it advances, and the land is leveled. The mat seedling on the seedling mounting table 9 is supported by the receiving surface 10b of the seedling receiving device 10 below, and slides on the receiving surface 10b as the seedling mounting table 9 moves left and right, but is turning. Since the tip of the seedling tool 11 descends through the seedling opening, the tip of the seedling tool 11 is sequentially cut laterally from the lower end and inserted into the mud surface, and the transplanting operation is performed.

Here, the seedlings inserted into the mud surface may be tilted forward or backward due to the turning speed of the seedling-planting tool 11 (inter-strain adjustment). Inner wire
Loosen 21. Then, the lever 15 is pulled by the spring 17 and the lower part moves forward, and the link 19 turns the seedling receiver 10 downward. Therefore, the lower end of the mat seedling supported by the seedling receiving device 10 is tilted more backward than before, and the posture taken out by the seedling planting tool 11 and inserted into the mud surface is adjusted to the upright side. Is done. When the seedling is tilted backward, the operating rod 23 may be operated in reverse.

And in carrying out the present invention, the angle of the seedling receiving device 10 is:
Because it changes in conjunction with the control device between the stocks,
It is convenient.
